(01. 15262) This invention relates to mop wringers and In the drawings 8 denotes a suitable vessel devices intended to force liquids out of pliable such as a pail or bucket into which the mop is to substances by compressing the same and has be rinsed and wrung out. The vessel 8 is provided for an object to provide a device of this charwith a rirn 10 here shown as a rolled or turned '5 acter which can be placed upon a pail, bucket or back rim, and a bail 11 for carrying the vessel. 60

The rotational movement of the member 110 erence is had to the accompanying drawings, in which Figure 1 is a side elevation of the wringer 20 is limited to a convenient distance by suitable means such as the stop suitably secured to the member 14 at 46 as by riveting.

For convenience in handling and storing the mop wringer, the rollers may be secured in a closed position by some suitable means, such as the hook or latch 50 pivoted at 51 on one of the U-shaped members 14 and engaging a stud 52 upon the other U-shaped member 2c.

In operation a mop wringer made according to this invention is placed upon the upper rim 10 of a vessel in such manner that the shaft 16 rests upon said rim with the roller 15 partly within the vessel and with the other end 17 of the wringer resting upon the floor. The member 20 carrying the roller 25 is caused by the spring means 41 to assume a position in which the rollers are spaced apart substantially as in Figure 1. In this position a mop, rag or other article 12 to be wrung out may be dropped between the rollers 15 and 25 and allowed to fall into the bucket sufficiently far so that the portion clamped by the mop handle is above the roller 15. When the mop is in this position, an application of downward pressure upon the rung 24, conveniently effected. by the foot of the person operating the wringer as indicated by the dotted lines in Figure 2, causes the member 20 to force the roller 25 to close upon the roller 15 and compress the mop as in Figure 2.

When the rollers 25 and 15 have compressed the mop or other article between them, pulling the same upward and through the said rollers squeezes out the water or other liquid desired to be expelled, into the bucket below. The release of downward pressure upon the rung 24 permits the rollers to open and separate because of the spring means 41 and the mop may be reintroduced and dropped through the rollers into the water or liquid in the vessel again and rinsed by agitating and then wrung out a second time by drawing upwardly through the rollers and compressing the same as heretofore described. If it is desired to wring out the mop a second time without withdrawing the same entirely from between the rollers the pressure exerted upon the rung 24 may be released sufficiently to permit the spring 32 within the roller 25 or 15 to cause the same to rotate in a direction so as to reintroduce the mop into the vessel as a result of the spring 32 having been tensioned by the previous withdrawal of the mop and the counter motion of the rollers. The spring and its manner of attachment is illustrated by a cut-away section of the roller 25 and it will be understood that the complementary spring arrangement may be carried in the other roller with the necessary reversal of arrangement in order to make the rollers cooperate to draw the mop down into the vessel. If the springs 41 are insufiicient to separate the rollers, or if the said springs are omitted entirely, the rollers may be separated by applying pressure as by the heel of the foot, to the lower end 22 of the member 20. It will be understood also that the rung 24 may be located higher up to increase the action of the rollers 15 and 25 with a given amount of pressure.

It will be appreciated that the features of this invention may be reproduced with many variations in shape, size and arrangement of the constituent parts and no limitation is intended by the exact form shown in the drawings herewith nor in the relative size of the parts and distances between the same.

To assure that all portions of the mop be confined between the two rollers 15 and 25 during the wringing operation I provide suitable guards 53 preferably mounted upon and projecting laterally from shaft 16. When such guards are employed it is, of course, important that the shaft 16 be mounted with little or no rotation relative to the U-shaped member upon which they are mounted.

What is claimed is:

l. A mop wringer comprising a roller rotatably carried by a frame upon an end, means carried with said roller end of frame for resting upon the rim of a vessel, means carried at the other end of said frame for resting upon a supporting surface for the vessel, a roller rotatably carried upon a frame pivotally connected to the first named frame for contact with the first named roller, and a force transmitting member carried by the last named frame between the pivot and the roller carried by said frame.

2. A mop wringer provided with a pair of rollers rotatably carried upon frames pivotally connected for contact and retreat of said rollers, means carried by one of said frames for support of the mop wringer upon the rim of a vessel and upon the surface supporting said vessel, a force transmitting member carried by the other said frame between the pivotal connection and the rolller through which pressure applied thereto is adapted to bring said rollers into contact, and means to cause said rollers to retreat with respect to one another when said pressure is removed.

3. A mop wringer comprising a U-shaped member for straddling a pail, one end of which is adapted to rest upon the floor and the other end of which is provided with a shaft which rests upon the rim of said pail, a roller rotatably mounted upon said shaft and located within the rim of the pail, a companion U-shaped member pivotally mounted upon the first named member towards the lower end of the latter and provided with a roller at its upper end, and means located upon said second member above said pivot for applying pressure to said member to effect a relative movement of one of said rollers toward the other.

4. A mop wringer comprising a U-shaped member for straddling a pail, one end of which is adapted to rest upon the floor and the other end of which is provided with a shaft which is adapted to rest upon the rim of said pail, a roller rotatably mounted upon said shaft and located within the rim of the pail, a companion U-shaped member pivotally mounted upon the first named member near the lower end of the latter and provided with a roller at its upper end, means located upon said second member above said pivot for applying pressure to said member to effect a relative movement of one of said rollers toward the other, and means on one of said members cooperating with the other member to limit the amount of separation between said rollers.

A mop wringer comprising a U-shaped member for straddling a pail, one end of which is adapted to rest upon the fioor and the other end of which is provided with a shaft which is adapted to rest upon the rim of said pail, a roller rotatably mounted upon said shaft and located within the rim of the vessel, a companion U-shaped member pivotally mounted upon the first named member near the lower end of the latter and provided with a shaft at its upper end, a roller rotatably mounted upon said shaft, there being spaces between the ends of the roller and the ends of said shaft to enable the lower side of the roller to be moved into a plane below the surface of the pail, and means located upon said second member above said pivot for applying pressure to said member to effect a relative movement of one of said rollers toward the other.

6. In a mop Wringer, a plurality of frame mem bers in pivoted relation, a mop compressing member carried by each frame, and at least one force transmitting member carried by one frame member upon each side of the pivot.

7. In a mop Wringer, a plurality of frame members, a mop compressing member carried by one end of each frame member, said frame members pivoted remotely from the mop compressing members, and at least one force transmitting member carried by one frame member upon each side of the pivot.

8. In a mop wringer, a plurality of substantially U-shaped frame members pivoted adjacent the base portion of the U, a plurality of mop compressing members carried by each frame member adjacent the open end of the U, a force transmitting member carried by one frame member between the pivot and the mop compressing member to urge the same toward the other mop compressing member, and a force transmitting member carried. by the last named frame member upon the side of the pivot remotely from the mop compressing member to separate the mop compressing members.
